Holds its charge really well!
By T. Allen on Reviewed in the United States on July 9, 2025
After I bought this thing, I stuck it in my backpack which is equipped with an external USB connection for connecting to a charger just like this...and promptly forgot it. About six months later, digging in the laptop I found it and pressed the power indicator button expecting it to show one or two bars missing but nope! Full power. Additionally when using this to recharge my Android or my wife's iPhone after a days use out camping, there are still a full four bars of energy left. Only time I saw this thing go down a bar in capacity was after a recent camping trip where it fully charged my wife's phone TWICE and mine as well one time. The one minor issue I have is the charging speed. It isn't great, taking over an hour for 50%...longer still if you are using it at the same time, of course. I'm buying a second one for the kids to use on our upcoming week long trip to the middle of nowhere. The ability to charge two devices at once is handy!

It's not as waterproof as led to believe.
By Robert Carnevali on Reviewed in the United States on June 4, 2025
It was a beautiful day and I really wanted to see how much of a charge this would get from being in direct sunlight for a few hours. I drained it and didn't expect a large battery like this to charge in an afternoon without a much larger solar cell, but I was curious how much of a charge it would get. I did get a charge and estimate about 25% with four or five hours of strong direct sunlight. I'm not unhappy with that. In an emergency, it could be used to boost a cell phone or other electronic device. It does have two USB-A charging ports and a USB-C port too. The flashlight is an added bonus just in case you do need light. But while I was out running an errand, clouds quickly came in and there was a downpour for ten minutes or so. I couldn't get home in time to prevent it from getting wet, and water did get inside the unit. The USB ports were soaked, water was condensing on the inside of the flashlight, and water was very much within the unit. It must have shorted out the batteries a little bit because the flashlight came on a low power. I was able to turn it on full power and "off" again, though for a day, it kept running at a low power. I wanted to open it by removing the four screws on the back of the unit so it would dry out faster. That was when I found out those "screws" were actually just a decorative design element molded into the case to look like screws, which is stupid. Why mold plastic to look like screws and that it could be opened when it can't. I then pulled out the orange silicon bumper along both edges, exposing slots the silicon fitted into. This let me place it outside in a nice breeze so that air was blowing through it (it was a windy day). It dried out quickly, the flashlight started working, and it works fine again. The problem is I can't get the silicon bumper back in. It's partially in enough to stay in place but looks clumsy. It's functional, and the solar cell does let you charge to about 75% over a couple days, making it useful in a real emergency should you not have power for days. but do NOT count on it being IP67 waterproof. It most definitely is not, it will fill with water, and functionally will be affected.
